It's the same day Trump is scheduled to hold a fundraiser for his campaign at the Columbia Club in downtown Indy, and the rally also happens as speculation swirls around Governor Pence and whether he might be asked to be Trump's running mate.

When asked by RTV6 on Monday, Pence said he will introduce Trump at the rally.

The Trump campaign has been vetting Pence along with a handful of others, and Pence and his family visited Trump at Trump's New Jersey golf course last weekend.

While the governor has heretofore claimed to be committed to his re-election campaign in Indiana, he has not denied interest in the number two slot on the GOP ticket, though he has often used the phrase "nothing was offered, nothing was accepted" to describe his conversations with Trump.

Trump's Indiana rally will also take place three days before the deadline for Pence to remove his name from the Indiana ballot, since state law bars him from running for governor and vice president simultaneously.
